Polymarket indexers and on-chain data tools
Use indexed blockchain activity without building the whole indexing pipeline yourself. Tools turn contract events into datasets, queries or streams for prediction-market applications.
How to choose on-chain data
Choose the data workflow
- Query decoded trades and market events.
- Track positions and participant activity.
- Deliver indexed changes to an application or warehouse.
Check what the source represents
Compare contract coverage, response schema, historical reach and delivery method. An on-chain trade stream describes different data from the exchange’s resting order book. Select the source needed by your application rather than substituting one for the other.
